Linear Post Regulation for Unrivalled Performance
The heart of all TSX series PSUs is an innovative regulator design which combines switch mode pre-regulation with linear post-regulation.

The pre-regulator uses specially developed techniques to dramatically reduce the capacitance between input and output thus eliminating the high levels of common-mode noise normally associated with switch mode PSUs.

The linear post-regulator combines very low levels of output noise with excellent load regulation and transient response. The result is performance comparable with a pure linear design.

Compact and Lightweight
The hybrid regulator design provides a PSU which is both smaller and lighter than competitive products. The high thermal efficiency also means that the PSUs are silent in operation since fan cooling is unnecessary.

Bench or Rack Mounting
The attractively styled casing takes up very little bench space and incorporates a tilt bail to angle the front panel when required. The case is half rack width (3U height), an optional (sold seperately) rack-mount kit is available.

Output terminals are fitted at both front and rear.

Constant Voltage or Constant Current Operation
All TSX series PSUs can operate in both constant voltage and constant current modes with automatic crossover and automatic mode indication.

High Accuracy Metering
The TSW power supply incorporates high resolution digital meters for both voltage and current.
V and I levels can be set to high accuracy prior to connection to the load and the limit settings can be checked at any time.
A damping switch for the current meter enables the average value of rapidly
changing currents to be read.

Full overvoltage protection
The TSX power supply incorporates a fully variable OVP trip to protect against regulator failure. The output is fully protected and other protection functions include regulator over temperature, and sense miswiring.
